JAMES REAGAN DALY, OF NEV ORLEANS, LOUISIANA.

ANTI-FLUCTUATOR FOR GAS-ENGINES.

SPECIFICATION forming part of Letters Patent N o. 392,109, dated October 30, 1888. Application filed March 17, 1888. Serial No. 267.554. (No model.)

To all whom. it may concern:

Be it known that I, JAMEs REAGAN DALY, a citizen of the United States, -residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and use ful Improvements in an vAnti-Fluctuator for Gas-Engines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in anti-fluctuators for gas-engines; and its object is to provide a simple device whereby the engine is made to operate in a uniform or steady manner, the exhaustion of gas by each stroke of the engine being replenished by a continuous iiow of gas into a tank in such manner as to maintain an even pressure.

In the drawings, Figure lis a side elevation of the improved device. Fig. 2 is a vertical section of the same, and Fig. 3 is a plan view of the same.

The body A of the device may be of any suitable shape, preferably cylindrical, and is provided with a removable cover, C, held in place by thumb-screws M.

Vithin the body A is a bell, B, closed at the top and there provided with a central guiderod, E, which extends upward from the bell and through an opening in the cover C, apacking nut or shoulder being used, if desired.`

Within the bell the rod E or another rod may be continued downward,terminatingin a head, F. The body is supplied with water, oil, glycerine, or other iiuid, to a height sufficient to seal the bell B, a water-line screw, K, being provided to limit the said height, if desired. The body is provided with an inlet-pipe, G, and outlet-pipe H, both of which may enter through the bottom of the said body, and which extend upward above the iiuid-level, the outlet-pipe being the higher. The inlet-pipe G is provided on its upper end with a valve, J, on one end of a lever, J, the other end being controlled by the head F, before referred to. The valve may be constructed to be closed by gravity, or other suitable means may be employed to close it when the bell is raised by gas-pressure. The inlet-pipe is provided with a bypass pipe, I, extending from a pointbelow the valved end of the said inlet and opening into the bell, a suitable Valve, I', being employed to regulate the passage of gas therethrough. 'Ihe bellis provided with rollers T, traveling on guide-tracks S on the inner surface of the body, and the cover carries hurting-springs D, against wh'ich the bell engages when raised high enough.

IVhen the gas enters the bell through the iulet G, it is raised and the valve J is closed. The supply then passes through the by-pass pipe I, the weight ofthe bell maintaining an even flow through the outlet H. Should the inliux of gas through pipe I be insufficient from any cause to maintain the requisite pressure, the bell will fall until the valve J is opened and the full supply resumed.

Having described my invention, what I claim is- In an anti-ductuator for gas-engines, the combination, with the body A, having the central aperture in its top, and the buffer-springs D, depending from the under side thereof,and the tracks S in the vertical walls of the bell B, having friction-rollers to engage the said tracks Within the body,of the inlet -pipe G, opening into said bell, the valve J, fulcrumed at the upper end of the said inlet-pipe and within the bell, the rod E, connected with the said valve-rod and passing through apertures in the roof of the body and also the bell, the bypass pipe connected with the inlet-pipe below the body and its opposite end opening into the bell above the water-line thereof and having a cock, I', and the outlet-pipe passing through the body and into the bell at a greater height than the inlet-pipe, all adapted to operate substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES REAGAN DALY.
